ABSTRACT:
A system for removing fumes from the space above a cooking surface includes a hood, having front and side wall panels located above said cooking surface and covering the space above said cooking surface. The front wall panel is located forwardly of said cooking surface to form an entrainment chamber between said hood and said cooking surface. The entrainment chamber is in communication with air intake means and an exhaust means. The air intake means comprises an intake blower for introduction of air from the outside into a pressurized plenum located above said cooking surface. The pressurized plenum includes an air distribution baffle and an air velocity valve assembly, which opens into said entrainment chamber. The rear surface of said front panel supports an air foil, located below the air velocity valve assembly. The air foil extends across said hood, and projects at an acute angle toward the cooking surface. This directs the diffused air pattern from said air velocity valve assembly toward the fumes rising from said cooking surface, for mixture in the entrainment chamber. Exhaust means in operative relation with the entrainment chamber, removes the fumes and air mixture. The exhaust means includes an exhaust duct, an exhaust blower and a filter situated between said entrainment chamber and said exhaust means.
